Senior Integrations Engineer Europe

Our client is a purpose-driven software company focused on the social impact sector, building innovative SaaS solutions that empower nonprofits, donors, and communities to operate more efficiently and maximize their impact.

We’re hiring an experienced Senior Integrations Engineer who will build and productize the integration layer for a CSR platform — connecting it to enterprise HRIS systems, CRM platforms, nonprofit databases, and internal product APIs. The work is highly API-driven: designing connectors, developing bi-directional synchronization engines, and ensuring data consistency across systems.

• HRIS connectors for Workday, SAP Success Factors, and other major providers (employee lifecycle sync, org hierarchy mapping)
• Salesforce integration: account/opportunity sync, NPO data sync, bi-directional field mapping
• Webhook infrastructure for event-driven cross-product communication
• REST API endpoints with OpenAPI documentation (Redocly)
• Cross-product data linking (tenant mapping across platform products)

• Expert use of AI-assisted development tools (Copilot, Claude, Cursor, or equivalent)
• REST API design and implementation (OpenAPI/Swagger)
• Type Script / Node.js
• Salesforce API integration (REST, Bulk API, Streaming API)
• HRIS integration patterns (SCIM, flat file, API-based)
• Webhook design and reliable delivery patterns
• AWS Lambda, API Gateway
• OAuth2 for third-party service authentication

• Microsoft Dynamics 365 integration
• ERP system integration (SAP, Oracle)
• Experience with NPO/nonprofit data standards
